What is the difference between microtubules and microfilaments?

∙ 13y ago
microtubules and microfilaments are alike in some ways, but are NOT the same. Microtubules are the building blocks to actin and provide structure and cell strength. They are thinner in relation to microtubules.
Microtubules are made from tubulin, and are seen in different cell function, such as mitosis (extend from centrosomes to attach to centromere kinetechore), reproductive system (making up flagella that move sperm or cilia in fallopian tubes to catch/move the egg) and respiratory system (cilia in the lungs to remove debris and keep lungs clean).

∙ 13y agoMicrotubules participate in a wide variety of cell activities. Most involve motion. Made up of alpha and beta tubulin.
Microfilaments provide mechanical strength to the cell andare relatively thin compared to microtubules.They also link transmembrane proteins (cell surface receptors) to cytoplasmic proteins. They anchor the centrosomes at opposite poles of the cell during mitosis and pinches during cytokinesis They are made up of protein actin.

What protein fiber is used for cellular movement and are extremely thin in size?
Microfilaments and Microtubules are involved.
Microtubules and microfilaments are made from proteins that are shaped like .?
balls
Do plant and animal cells have microfilaments?
Yes, plants have microtubules. Microtubules are hollow tubes composed of a protein called tubulin. They are the thickest and most rigid of the filaments.
Microtubles and microfilaments are made from proteins that are shaped like?
Microtubules 50nm, make up the larger part of the cytoskeleton, and they are hollow, and larger. Microfilaments 8-10 nm are smaller, they are in a double helix shape, different from microtubules.
What is the most stable microtubules microfilaments or intermediate filaments?
Intermediate filaments are the most stable.
What structures carry out cell movement?
a. cytoplasm and ribosomes b. nucleolus and nucleus c. microtubules and microfilaments d. chromosomes answer is c. microtubules and microfilaments
What are 3 protein fibers found in cytoskeleton?
1. A network of microtubules mainly in ectoplasm2. cytoplasmic network of microfilaments (actin filaments)3. Intermidiate fillamentsthe main protein of cytoskeleton are tubulin, actin, and myosin.
How do microfilaments and microtubules differ from each other?
Microfilaments are thinner rods of protein that enable movement. Microtubules are hollow tubes that give rigidity and shape. Flagella and cilia have microtubules in their centers.
What is the cytoskeleton and what are the two of its major components?
The cytoskeleton is a network of filamentous proteins that holds the organelles in place and maintains the shape of a cell. It is composed of microtubules (composed of the protein tubulin), intermediate fibers, and microfilaments.
What material are microtubules composed of?
Microtubules are polymers of tubulin. Microfilaments are polymers of actin.
Microtubules and microfilaments form the cytoskeleton of cells?
that is true
What protein fiber is used for cellular movement and are extremely thin in size?
Microfilaments and Microtubules are involved.
Which structure carry out cell movement?
Microtubules and Microfilaments.
What all are parts of the cytoskeleton?
Microfilaments, Intermediate filaments, Microtubules
Microtubules and microfilaments are made from proteins that are shaped like .?
balls
What two parts make up the cytoskleton?
Microfilaments and microtubules
What is the function of a Microfilaments in a plant cell?
in cells, microfilaments support cytoplasm and microtubules transport materials within cytoplasm
